OCTAVE INTERVALS
An octave is a thoroughly consistent interval: basically, going from one letter to its namesake (either one octave higher or lower) in any scale will always involve travelling an interval (distance) of 12 semitones (or six tones).
The waveforms created by octaves are more stable and therefore less dissonant than other intervals because it is perfectly divisible (a note an octave higher is exactly twice the frequency and vice versa), and so notes an octave apart work well when played simultaneously, even with distortion.
Once you have absorbed the various concepts featured within this lesson’s demo examples, you should aim to apply the same principles to every pattern of the other scales that you know - shifting ideas up and down the length of the neck (lateral motion), as well as staying within the same neck area (vertical motion) - in order
